We’ve set higher standards for
prenatal nutrition.

Prenatal vitamins are one of the most important, yet least regulated and optimized, supplements on the market. Most deliver only a fraction of the essential daily nutrient recommendations for a healthy pregnancy.

We partnered with the Neurological Health Foundation and leading prenatal nutrition researcher Dr. James Adams to develop a research-backed, trimester-specific system designed to evolve with the changing physiological and neurological demands of pregnancy and gestation.

At Healthynest, we source the highest quality, most bioavailable raw ingredients from reputable suppliers. Each trimester of Our Prenatal is third-party tested for heavy metals and microbes and inspected for quality before and after encapsulation—every single time we make them.

KEY INGREDIENTS

We source the highest-quality vitamins, minerals, and DHAs, and deliver them in forms for optimal absorption.

Iron 26.67 mg

Iron-deficiency anemia is extremely common in women who experience excessive blood loss during delivery or postpartum hemorrhage. Oral iron supplementation during T4 can help recover these losses.

B12 16 mcg

Infants of lactating mothers who are deficient in Vitamin B12 may develop anemia or exhibit neurological abnormalities. Vitamin B12 levels are reduced in the breast milk of mothers who follow vegan diets or other restrictive diets that exclude meat, chicken, fish or dairy.

D3 22.2 mcg

Low levels of Vitamin D have been associated with a higher likelihood of PPD.

Vitamin C 89 mg

Vitamin C is responsible for synthesizing collagen and is necessary for proper wound healing.

Calcium 155.56 mg

Calcium is a building block for baby’s bones, nerves, and muscles. Levels of total calcium and bone density decline throughout pregnancy, so calcium supplementation is critical. Calcium works synergistically with vitamin D to increase absorption.

Selenium 31.1 mcg

Selenium supplementation has been shown to reduce hypothyroidism, pregnancy-induced hypertension, preeclampsia, and postpartum depression.

Zinc 13.33 mg

Zinc has many roles in the body, including immune function, growth and development, nerve function, vision, and fertility. Zinc is recommended for reducing the risk of preeclampsia and preterm birth, as well as asthma in infants.

"There is a significant gap between what the science recommends and what most prenatal supplements deliver. Many are designed to meet minimum nutritional standards, but pregnancy is not a minimum moment. An optimized, evidence-based approach to prenatal nutrition—starting even before conception—has the potential to meaningfully improve outcomes for both mother and baby."

“I recently started preparing my body with these prenatals. They've been so helpful, and I feel confident I won't have a miscarriage again. Although it's a lot of pills, I don't personally mind since they're split throughout the day and I know I'm on the right track of getting all the nutrients.

The scientific evidence based research paper that I was able to look into was the reason that made me buy these prenatals. Every other prenatal on the market falls short in vitamins.”

FAQs

Is your prenatal tested for heavy metals?

Yes, we take the safety of our formulations very seriously. Our Prenatal is tested for heavy metals (arsenic, lead, cadmium, and mercury). We screen our ingredients before and after production and then test all finished products to ensure we meet our high safety standards.

Are your prenatals gluten-free and major allergen-free?

Our supplements are gluten free, but not allergen-free. Our fish oil softgels contain fish (anchovy). Our dry powder capsules are free from milk, eggs, shellfish, wheat, gluten, peanuts, soy, and tree nuts.

Are your prenatal vitamins organic?

Minerals are naturally occurring, but technically not organic, because they'e not derived from living organisms.Our Prenatal includes minerals and therefore can’t be organic.

What makes your prenatal supplements different?

Unlike other prenatals that consist of the same formulation throughout pregnancy, Our Prenatal is customized for the evolving needs of your body, with 12 of our 27 ingredients changing by trimester. Our Prenatal formulation was informed by over 350 peer-reviewed research studies. Additionally, we've selected the most bioavailable forms of each vitamin and mineral, so your body can easily absorb and utilize nutrients.

Does your prenatal contain DHA?

Yes, Our Prenatal contains 500 milligrams of DHA and 250 milligrams of EPA from fish oil per day for Trimesters 1-3. This increases to 650 milligrams of DHA and 1,000 milligrams of EPA per day for Trimester 4.

Is your prenatal approved by the FDA?

The FDA doesn't regulate prenatal vitamins or any other dietary supplements, which is why it's important to do your research. In the absence of regulation, we comply with the FDA's good manufacturing practices and maintain our own strict safety standards.

HealthyBaby Chief Innovation Officer Hilary Swank testified in support of California Senate Bill 646, which will require prenatal vitamin manufacturers in the state to test a representative sample of their products for heavy metals, including arsenic, cadmium, lead, and mercury, and to make these test results publicly available to consumers. SB646 passed in September 2025, and we hope it inspires more widespread safety regulation of the prenatal and supplements industry.

What are “bioavailable nutrients”?

Some forms of vitamins and minerals are absorbed better than others, because they require less processing by the body. For example, folic acid is the synthetic form of folate. To become active, or bioavailable, the body must convert the folic acid to methylfolate. Our Prenatal uses the bioavailable form methlyfolate, so your body can absorb and utilize the nutrients more easily.

If I forgot to take my prenatal for one day, should I take a double dose the next day?

We don't recommend taking an extra dose. We recommend keeping the morning and afternoon doses apart by several hours for best absorption. Supplements are designed to build a baseline of nutrition. If you miss a dose, no problem! Just continue your normal regimen.

Do I need to take a multivitamin with the prenatal?

We’ve developed Our Prenatal to be a comprehensive multivitamin (with a softgel containing both DHA and EPA) that will meet the nutritional needs of most pregnant and lactating women. In almost all cases, this prenatal should replace a general multivitamin. Please make sure it's appropriate for your needs by consulting with your physician.

Is it possible to take too many vitamins?

Yes. The amounts in Our Prenatal are generally safe and within the Tolerable Upper Intake Limits established by the FDA. However, taking excessive amounts of vitamins (especially fat-soluble vitamins, including vitamins A, D, E, K) and minerals may be harmful. Before taking any other supplement along with our prenatal program, please review our label and consult your physician.

How should I take this prenatal? Does it contain folic acid?

We've designed Our Prenatal to be taken as two servings per day: one in the morning (typically taken with breakfast) and another in the evening (typically taken with dinner). We don't include folic acid in Our Prenatal, as it is a synthetic form of folate, and people vary greatly in their ability to convert it to bioactive forms. Instead, we use the bioavailable form 5-methyl-tetrahydrofolate (5-MTHF) to make sure your body can absorb it. We recommend consulting your doctor before taking Our Prenatal to ensure it meets your needs.

What are the other ingredients not in the nutritional panel?

Our other ingredients include the vegetarian capsule (modified cellulose, water), magnesium stearate, silicon dioxide (silica), and cellulose. The softgels contain fish oil from Peruvian anchovies and are made with gelatin, glycerin, and purified water.

“After my first child was diagnosed with autism, I wanted to do everything I could to ensure the neurological health of my second. I turned to Dr. Adams to tailor a program for me that would create the optimal environment for my baby during pregnancy. Every mom should have access to this knowledge and it should be easy, so I’m proud to collaborate with the Neurological Health Foundation to distill Dr. Adam’s’s work into one comprehensive and easy prenatal system.”
